he circuit has been increasedin the same ratio as the total E. M. F. But ifthe external resistance is large, the current pro-duced by the combination will be very muchgreater than that produced by a single cell. Justhow much greater can always be determined by applying Ohms law,for if there are n… … Fig. 53. Cells Connectedin Parallel. c = nE Re + nRi If the n cells are connected in parallel, that is, if all the coppersare connected together and all the zincs, as in Fig. 52, the E. M. F. ofthe combination is only the E. M. F. of a single cell, while the internalresistance is 1/n of that of a…
